I'm sorry you're having trouble.
Grepping the source tree on 6.2-RELEASE shows this message can only have com from one place : sys/kern/kern_conf.c in the function prep_cdevsw() : if (devsw->d_version != D_VERSION_01) { printf( "WARNING: Device driver \"%s\" has wrong version %s\n", devsw->d_name == NULL ? "???" : devsw->d_name, "and is disabled. Recompile KLD module."); Looks like the kernel and the modules are out of sync. > On 2/24/07, Joe Auty <[EMAIL PROTECTED]> wrote: > > Hello, > > > > (sorry, don't know whether kernel problems should go to questions or > > hackers, or both).. > > > > This has been a long-standing problem of mine, but I always ignored > > it hoping it would go away on its own with a future 6.x release, but > > it remains... > > > > No matter whether I boot into safe mode or regular mode, with all > > kernel extensions disabled in /boot/loader.conf, I get the following > > panic late at boot of a fresh RELENG_6_2 kernel (with only a few > > services left to bring up).
